Really nice work jistme!
Love that aqua green you used. And that splash screen!!!!
The whole skin has got that neon vibe.
If I could make one little constructive suggestion.
<element id="Panel.ChildHeader.Default" bg="?,?,?" fg="0,0,0" bdr="?,?,?" />
the fg might need to go to "5,43,41" or "9,64,60". The black is really hard to see on "Track Information"
